I really don't think there's anything "wrong" with my heating system. True, i could probably use a flush, the last time it had been done was 2 and half years ago and a TON of stuff came out. But, the jeep does get warm, if it's 30* out it can get warm enough to drive in a sweatshirt. The difference between her jeep and mine is that she can achieve a hotter temp at a lower fan speed in a shorter amount of time where as mine will take longer to warm, will be comfortable/warm..not hot like hers (at a point where she needs to back it down cause it's so hot) and mine will require it to blow at 3rd level rather than 1 or 2.
anyway, with a flush, it would prob heat like hers, but i was just wondering if there was anything out there better than stock. I figure if I want to start wheeling in more adventurous settings, i could possibly end up in colder regions and may welcome a stronger heater.
